Jiexinsheng Home Security Driveway Alarm,Door Bell Chime with 1 Plug-in Receiver and 2 PIR Motion Sensor Detector Alert System, 38 Chime Tunes - LED Indicators

These worked very well to help us know when our toddlers had gotten up and wandered around at night. You can avoid setting them off if you know they are there and move very slowly though.

The product was as advertised. It was set up to be a deterrent to unwanted visitors at night who are prowling the neighborhood.

We like it but just wish it didn't go off all the time when the clouds come over...

Has limited range. Will not picked very well unless is close, maybe 15 feet if there is a wall between

I used this products to alert me someone interning my property, thanks

Like a reviewer put on this website they work great for his mailbox. That would be an inside installation. Outside I put them in a few different spots. Constantly went of with false alarms. I do not recommend this for outside use anywhere.

It says there are 36 different chimes to chose from. ALL 36 are super harsh & irritating and just plain stupid. Like tinny versions of the happy birthday song, Fur Elise, mariachi and other chimes you would never want to listen to.

I like the way it knows, which sensor to sound off.
